D-17. Local security prevents a unit from being surprised and is an important part of maintaining the initiative. Local security includes local measure taken by units against enemy actions. It involves avoiding detection by the enemy or deceiving the enemy about friendly positions and intentions. It also includes finding any enemy forces in the immediate vicinity and knowing as much about their positions and intentions as possible. The requirement for maintaining local security is an inherent part of all operations. Table D-2 lists a sample of active and passive local security measures.
